Jonah, like Joel before him, is a talented inventor. But who's the better inventor between them? Joel made levers that could alter reality, and created Tom, Crow, Gypsy and Cambot, who feel more like humans than robots. On the other hand, Jonah gave Tom the ability to fly (albeit only in the theater), and in the Invention Exchanges, his inventions are a little more practical than Joel's. The Swiss Army Cheese, for example, which tells you what wine goes best with the cheese you're eating, could actually be useful. Jonah also invented verbal smoke bombs, for avoiding awkward conversations. Most of Joel's inventions are either puns or gags, which makes sense, as Joel was a prop comic prior to MST3K.
